ACPL-351J-000E

Overview

The ACPL-351J-000E is a single-channel logic output optocoupler designed for gate drive applications. It features a wide operating supply voltage range of 15V to 30V and provides high peak output currents of 4.5A for both sourcing and sinking. The device offers an isolation voltage of 5000Vrms and a minimum common mode transient immunity of 100kV/µs. Propagation delays are limited to 150ns, with pulse width distortion capped at 50ns. It operates within a temperature range of -40°C to 105°C.

Feature Summary

• High peak output current capability for driving power devices
• Robust common mode transient immunity for noisy environments
• Wide supply voltage range supporting various gate drive requirements

Applications

• Industrial power supplies
• Photovoltaic inverters
• On-board chargers
• DC motor control systems

Procurement Notes

Verify the specific suffix against official Broadcom documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints and thermal management strategies. Confirm that the 5000Vrms isolation rating meets the safety standards required for your specific application environment. Check for any recent product discontinuance notifications or lifecycle changes.

Selection Notes

Select this component when high-speed switching and robust isolation are critical for gate drive circuits. The 15V to 30V supply range accommodates standard IGBT and SiC FET drivers. Consider the 100kV/µs CMTI rating for applications with rapid voltage transients. Evaluate the 4.5A output current against the gate charge requirements of the target power devices.

Part Context

This part belongs to the ACPL-331J/351J series of high-performance gate drive optocouplers from Broadcom. These devices are engineered to replace traditional transformer-based gate drives in modern power electronics. They integrate LED input and high-current output stages within a single isolated package.

Replacement Considerations

ACPL-352J-000E is a documented alternative offering higher output current capabilities.
